Lights Tips for The Average Joe

What Makes LED Better than Conventional Lighting?

LED lighting or light emitting diodes is by far the most energy-saving and a smart solution when you compare it with those other methods of illumination available in the market today.

It started out by utilizing these diodes via a DC circuit to emit light to extend the battery life that is used for flashlights and other light emitting gadgets like cellphones and etc. Then it began to find its way to vehicular headlights by utilizing a specially designed reflectors to intensify its brightness and length of coverage but still maintaining its efficiency. There are many advantages to using LED lighting which can now be run from an AC supply. So before they were only considered to be DC devices operating from a few volts of direct current but now has a more robust application that requires the same amount of voltage such as the linear strip lighting systems around the outside of a building that stretches for a hundred meters. Since DC drives suffer power loss over distance it then brings a different consideration. So then it would require the use of a higher drive voltage once the voltages start to drop and so additional regulators need to be used to maintain the voltage. This is not necessary if you have AC or alternative current since it main maintain voltage despite distance. This has always been the problem with DC power and the reason why it is not being used to transmit power across our streets and cities.

Running LED lighting from an AC supply means producing DC power to operate yo LED lights. And there are several applications for this. Many stand-alone fixtures simply have a transformer between the wall socket and the fixture to provide the required DC voltage. And there are a number of companies that provide LED light bulbs that screw directly into standard sockets, but these invariably also contain miniaturized circuitry that converts AC to DC before delivering it to the LEDs. The upfront costs of these LED lighting are very expensive. Many would argue though that eventually it pays off because your power bill would decrease remarkably.

Another early form is what is called the ‘Christmas tree light’ approach. This approach uses multiple LEDs in series so that the voltage drop across the whole string equals the supply voltage.

Attempts at developing true AC LED are beginning but today we still have to wait for this big technological leap that is seen as an upgrade from analog to digital. And the advantages versus conventional lighting are so huge and of major benefit to both the user of this technology as well as our planet.
